Schemes for locating and fixing the object in self-centering mechanisms with a set of hidden bases

Abstract

The updated provisions of the basing theory and the updated composition of the bases are given: installation, guide, support, double guide, double support, and triple support. Base combinations form five sets, each of which can be implemented using explicit or hidden bases or their combinations. It is shown that basing an object with sets of hidden bases causes the greatest difficulties, and a feature of basing an object with hidden bases is determining the position of reference points using the contact points of the object, implemented by the installation elements. When basing an object with a hidden base, the position of the reference point is determined by a self-centering mechanism using the points of contact with the basing object. Various schemes of constructive solutions for basing and fixing objects in sets of hidden bases in self-centering mechanisms are considered.
